Eh, quite a poorly written article by FT.
The fall in share of nominal GDP for the past 2 years is mainly due to currency depreciation and lower than global average inflation in China. It's not gonna continue every single year.
Likewise, the temporary strong USD and high interest rates due to high inflation is not gonna continue in the US, and is definitely not going to happen every single year to close the gap in the difference in real growth rate.
Yet the author simply extrapolates them as a long term trend into the future and make a lazy conclusion that we've reached peak China.
